3.
Install the bench testing tool on
the transmission.
4.
Remove the
1/8-inch
pipe plug
at the transmission case. Turn the
front pump in a clockwise direction at
75-100 rpm until a regular flow of
transmission fluid leaves the hole in
the transmission case. This operation
bleeds the air from the pump.
5.
Install the pressure gauge (77820
or T57L-77820-A) as shown in Fig.
13.
PRESSURE TESTS
Turn the front pump at 75-100 rpm
and note the gauge readings. The
pressure readings on the bench test
must be within the limits as outlined
in Figure 13, for the engine idle check.
If pressure gauge readings are with-
in limits in all selector lever positions,
install the vacuum diaphragm control
rod unit.
COMMON ADJUSTMENTS AND REPAIRS
TRANSMISSION FLUID DRAIN
AND REFILL
Normal maintenance and lubrica-
tion requirements do not necessitate
periodic automatic transmission fluid
changes.
If a major repair, such as a clutch
band, bearing, etc., is required in the
transmission, it will have to be re-
moved for service. At this time the
converter, transmission cooler and
cooler lines must be thoroughly
flushed to remove any dirt.
When filling a dry transmission and
converter, install five quarts of fluid.
Start the engine, shift the selector
lever as outlined below, and check and
add fluid as necessary.
Following are the procedures for
partial drain and refill due to in-
vehicle repair operation.
C4 TRANSMISSION
1.
On PEA models, disconnect the
fluid filler tube from the transmission
oil pan to drain the fluid.
On PEB and PEE models, loosen
the pan attaching bolts to drain the
fluid from the transmission.
2.
When the fluid has stopped
draining from the transmission, re-
move and thoroughly clean the pan
and the screen. Discard the pan gas-
ket.
3.
Place a new gasket on the pan,
and install the pan on the transmis-
sion.
4.
On PEA models, connect the
filler tube to the pan and tighten the
fitting securely.
5.
Add three quarts of fluid to the
transmission through the filler tube.
6. Run the engine at idle speed for
about two minutes, and then run it at
fast idle speed (about 1200 rpm) until
it reaches it's normal operating temp-
erature. Do not race the engine.
7.
Shift the selector lever through
all the positions, place it at P, and
check the fluid level. The fluid level
should be above the ADD mark. If
necessary, add enough fluid io the
transmission to bring the level be-
tween the ADD and FULL marks on
che dipstick. Do not overfill the trans-
mission.
FMX OK C6
TRANSMISSION
1.
Raise the vehicle on a hoist or
jack stands.
2.
Place a drain pan under the
transmission.
3.
Loosen the pan attaching bolts
to drain the fluid from the transmis-
sion.
4.
After the fluid has drained to the
level of the pan flange, remove the
rest of the pan bolts working from the
rear and both sides of the pan to
allow it to drop and drain slowly.
5.
When the fluid has stopped
draining from the transmission, re-
move and thoroughly clean the pan
and the screen. Discard the pan gas-
ket.
6. Place a new gasket on the pan,
and install the pan on the transmis-
sion.
7.
Add three quarts of fluid to the
transmission through the filler tube.
8. Run the engine at idle speed for
about two minutes, and then run it at
fast idle speed (about 1200 rpm) until
it reaches normal operating tempera-
ture.
Do not race the engine.
9. Shift the selector lever through
all the positions, place it at P, and
check the fluid level. The fluid level
should be above the ADD mark. If
necessary, add enough fluid to the
transmission to bring the level be-
tween the ADD and FULL marks on
the dipstick. Do not overfill the trans-
mission.
OIL COOLER TUBE
REMOVAL AND INSTALLATION
When fluid leakage is found at the
oil cooler, the cooler must be re-
placed. Cooler replacement is de-
scribed in the Cooling System Section
of Group 11.
When one or more of the fluid
cooler steel tubes must be replaced,
each replacement tube must be fabri-
cated from the same size steel tubing
as the original line.
Using the old tube as a guide, bend
the new tube as required. Add the
necessary fittings, and install the tube.
After the fittings have been tight-
ened, add fluid as needed, and check
for fluid leaks.
VACUUM DIAPHRAGM
ADJUSTMENT NON-ALTITUDE
COMPENSATING TYPE
The C4 and C6 transmissions are
equipped with an adjustable vacuum
diaphragm assembly. A similar ad-
justable diaphragm has been released
for service with the FMX transmis-
sion. However, the FMX service dia-
phragm is not interchangeable with
that used on C4 and C6 models.
The vacuum diaphragm assembly
has an adjusting screw in the vacuum
hose connecting tube (Fig. 14).

FIG. 14—Adjustable Vacuum Unit
The inner end of the screw bears
against a plate which in turn bears
against the vacuum diaphragm spring.
All readings slightly high or all
readings slightly low may indicate the
vacuum unit needs adjustment to cor-
rect a particular shift condition.procarmanuals.com
